Job Description

At Sword, data powers our mission to build a pain-free world. The Platform Team is building the infrastructure that makes this possible, high-performance APIs enabling self-service data access for clinical, operations, and AI teams. We're moving from a traditional data warehouse to an end-to-end platform, and this role is central to that transformation.

Design and build the APIs that make data accessible across Sword. You'll own critical platform services, implement resilient workflows, and collaborate with Data Engineers to define contracts that scale. Requires production API experience and comfort working in regulated environments.

What you’ll be doing:

Design and build high-performance APIs in Go or Typescript, starting with Publish API, then Serving API and Jobs API.

Implement durable execution workflows using Temporal for reliable, auditable data orchestration.

Build resilient services with proper retry logic, circuit breakers, and rate limiting.

Develop the tracking and state management layer (MySQL) powering observability and SLIs.

Integrate APIs with Kafka for event-driven data ingestion and delivery.

Collaborate with Data Engineers to define data contracts and API specifications.

Contribute to the Developer Portal enabling self-service API access and documentation.

What you need to have:

Strong experience with Go; TypeScript experience valued for specific platform components.

Proven track record building production-grade REST or gRPC APIs.

Solid understanding of Kafka including producers, consumers, partitioning strategies, and at-least-once/exactly-once semantics.

Experience with relational databases (MySQL or PostgreSQL).

Understanding of API security, authentication, and rate limiting patterns.

Experience working in regulated or compliance-sensitive environments (healthcare, fintech, or similar).

Bonus: Experience with Temporal, Restate, or similar workflow orchestration systems.

Bonus: Familiarity with observability stacks (Prometheus, Grafana, OpenTelemetry).

Bonus: Background in data platforms or data infrastructure teams.

Mindset and Collaboration:

Service orientation: you build APIs that others love to use.

Reliability-first: you think about failure modes, retries, and observability from day one.

Cross-functional: you enjoy working with data engineers and understanding data problems.

Documentation mindset: you believe good APIs come with great docs.

Iterative: you ship incrementally and improve based on feedback.

To ensure you feel good solving a big Human problem, we offer:

A stimulating, fast-paced environment with lots of room for creativity.

A bright future at a promising high-tech startup company.

Career development and growth, with a competitive salary.

The opportunity to work with a talented team and to add real value to an innovative solution with the potential to change the future of healthcare.

A flexible environment where you can control your hours (remotely) with unlimited vacation.

Access to our health and well-being program (digital therapist sessions).

Remote or Hybrid work policy.
